The Mississippi Public Service Commission on Tuesday approved a package of Entergy Mississippi and Mississippi Power filings that staff said reflect higher projected fuel costs and periodic true-ups, while endorsing mitigation steps designed to lessen immediate impacts for customers.

Staff presenter Miss Myrick told the commission Entergy’s combined rider filings (MISO cost/revenue, grid modernization, power management, net energy metering and the ECR fuel rider) will change a range of factors beginning in February 2026. She said the MISO credit factor will move from -4.11249% to -2.39099% (a $24.3 million effect, about $2.27 on a 1,000-kWh residential bill), the GMR factor will fall roughly 0.17579 percentage points (about a $2.5 million reduction, ~23¢/1,000 kWh), and the PMR adjustment as revised will lower that factor and reduce the monthly impact by roughly $2.05 compared with the unmitigated filing.

"When the rate impacts of all the rider filings are combined, beginning with February billing, a residential customer using 1,000 kilowatt hours should experience an increase of $14.22 per month when compared to a January bill," Miss Myrick said, explaining the change is driven by a reduced over-recovery being returned to customers and higher forecast natural gas prices.

Commissioners pressed staff and Entergy on whether the increases stem from new, large industrial customers and whether retail customers are effectively subsidizing those users. Entergy attorney Alicia Hall told the commission the fuel-related riders at issue "are not being disproportionately impacted by the large customers" in Entergy Mississippi’s territory and that large customers "are also paying the same fuel cost." She added that some clean-energy revenue credits attributable to large customers are flowing to the benefit of all customers.

On Mississippi Power filings, staff presented accounting orders to defer the company’s sales-and-use tax settlement and to defer approximately $25 million of protected excess accumulated deferred income tax (ADIT) to a regulatory liability that will be returned to ratepayers in a future proceeding. Staff also presented Mississippi Power’s proposed FCR and ECM factors: the unmitigated calculation would raise rates by about $76.8 million (about $7.95 on a 1,000-kWh residential bill), but Mississippi Power proposed temporarily deferring $31.2 million of under-recovery to reduce the near-term impact to roughly $45.6 million (about $4.44/month on a 1,000-kWh bill). Staff recommended approval of those mitigated factors as reasonable.

All of the energy-related orders presented in the energy agenda were approved by voice vote: the Entergy items (items 1–5) and Mississippi Power’s accounting orders and mitigated FCR/ECM factors (items 6–8). Commissioners also noted staff will present annual independent fuel-audit results in a future docket (staff said audits occur annually and presentations are expected in the March docket).

What’s next: Staff will implement the orders and present any required audit reports and interim-adjustment requests in future dockets. The Commission noted the company may request interim adjustments under the ECR mechanism if actual fuel collections diverge materially from projections.

Votes at a glance: Orders for Entergy items 1–5 approved (voice vote); Mississippi Power docket 2025UA103 (accounting order for sales/use tax deferral) approved; docket 2025UA104 (ADIT regulatory liability) approved; docket 2025UN114 (mitigated FCR/ECM factors) approved.
